My cat loves these things, there is only one suggestion. Would make, the charge lasts quite a while, I was surprised at that. Of stuff in my apartment, so though I ordered two of these balls, she managed to lose both of them. I am a disabled individual, it is very difficult for me to get down and look underneath stuff too so I can find the balls. Perhaps if they gave out a periodic chirp of noise, it would help people, and might even excite the cat more, just a suggestion

It's a lot of fun the cats were kinda curious about it but they play with it and have fun

Best on carpet
